摘　　要：提出一种确定和辨识拓扑错误的方法。提出了基于新息向量的新息图,在其上可以根据支路扩展新息向量和估计潮流确定拓扑错误,而且还可以根据不良回路和差别向量对出现在拓扑错误支路上或其他支路上的坏数据进行辨识。文中给出了IEEE—30 和IEEE—118This paper proposes an innovation graph m ethod for the location and identification of topology errors. The innovation graph, which relies on the innovation vector, is first established. On the basis ofinnovation graph, the topology error can be identified according to the extended innovation vector as wellas estim ated pow er flow on the branch. The bad data appearing on the topology error branch or other places can be identified based on the bad loop and difference vector. Results on the IEEE-5 bus system are used to illustrate the m ethod. Its perform ances are highlighted via sim ulations perform ed on the IEEE-30 and IEEE-118 bus system s. This project is supported by the State Key Laboratory of Control and Sim ulationof Pow er System and Generation Equipm entin Tsinghua University ofChina.
